  • Patent number: 4251076
    Abstract: A spectacle-type frame has a pair of open frame portions with a first alignment bar mounted across them by means of which a golfer wearing the frame lines up the direction of travel of a golf ball between an adjacent point and a distant point. A pair of second alignment bars extend at right angles to the first alignment bar at the respective open frame portions. These second alignment bars form a single focus line with the golfer's eyes and the golfer lines up the face surface of a golf club with such focus line for causing a golf ball when struck to travel accurately along the line determined by the first bar. The first alignment bar is adjustable for positioning it in proper alignment with the golfer's eyes and the second alignment bars are adjustable to provide the common focus line with the golfer's eyes.
